        OpenSearch by default supports Approximate Search powered by nmslib, faiss
        and lucene engines recommended for large datasets. Also supports brute force
        search through Script Scoring and Painless Scripting.
        Optional Keyword Args for Approximate Search:
            engine: "nmslib", "faiss", "hnsw"; default: "nmslib"
            space_type: "l2", "l1", "cosinesimil", "linf", "innerproduct"; default: "l2"
            ef_search: Size of the dynamic list used during k-NN searches. Higher values
            lead to more accurate but slower searches; default: 512
            ef_construction: Size of the dynamic list used during k-NN graph creation.
            Higher values lead to more accurate graph but slower indexing speed;
            default: 512
            m: Number of bidirectional links created for each new element. Large impact
            on memory consumption. Between 2 and 100; default: 16
        Keyword Args for Script Scoring or Painless Scripting:
